Abstract

This report presents the liture study of impact Energy Absorption (IEA)Devices. Since the society newadays full with advance technologies especially in transportation vehicles, unexpected impact collisions may occur at any times and take aver thousands of human life. A Solution work out by the engineers and scientist was the used of impact energy absorber which were designed to minimize the impact force transfer to human body when unwanted collisions ofvehicles occurs. This knowledge about (IEA) is now attracted greater concern and interest by the society. From the gdneral review of the energy absorbers, IEA can be categorized into two categories concerned with structural and material the IEA can be shaped into tubes, frusta, struts, honeycomb, and sandwich plates. In this report, it presents the analysis from the compression test of each shape above. The load versus displacement graph obtained to study the energy absorbed by the structure with structure with different deformation modes which included inversion, splitting, axial crushing, lateral indentation and lateral flattening,The applications of the IEA device on the automobiles and road side barriers are included in this report. The details of the bumper test crash test of the automobole are also included.
